AWS_ERROR_MQTT_UNEXPECTED_HUNGUP can be caused by many things but it is most likely something wrong with a policy. If you don't have the correct policy attached to the device that you provisioned then it won't connect to IoT core and you will get this error. If you are still having problems please include more details about what you are trying to do and reproduction steps for the error that you are seeing.
